It is made convenient for the communications terminal to effectively manage access rights, and the management becomes simpler and easier to operate. Meanwhile, the communications terminal performs authentication on the unique identification information of the user identity, thereby making the authentication process more efficient and improving the security of the authentication process. Meanwhile, priorities of the access rights of users are set, so as to ensure that a user of a high priority has preferential access, thereby making the access rights management more user-friendly.

TECHNICAL FIELD

The disclosure relates to the field of communication, and more particularly to a communication User Equipment (UE), communication system, and method for authorization management.

BACKGROUND

A mobile communication UE, especially a smart phone, has a built-in hot spot function. in enabling a hot spot, various modes of authentication such as OPEN-NONE, Wi-Fi Protected Access with a pre-shared key WPAPSK, or the like may be chosen. With the OPEN-NONE, another user is not required to enter a password to access the hot spot, which is convenient but hard to manage, thus susceptible to traffic theft. With encryption-authentication modes such as the WPAPSK, there is likewise a risk of password leakage, in addition to a cumbersome access process.

An existing WiFi (wireless fidelity, 802.11b protocol) chip typically serves for basic access management such as access authorization, limiting a total number of accessing clients, etc. For example, in access authorization, also commonly known as the blacklist/whitelist function, when a whitelist is enabled, only a user in the whitelist is allowed to access the hot spot; when a blacklist is enabled, a user in the blacklist is not allowed to access the hot spot. However, in bottom-layer implementation of the WiFi blacklist/whitelist, a Media Access Control (MAC) address serves as an identifier; while a mobile UE as a hot spot features portability and mobility, with a random and unpredictable accessing user, such that it is difficult to acquire and manage a MAC address. Thus, enabling a hot-spot MAC-based blacklist/whitelist function on a mobile communication UE poses poor usability and complicated management for common users. Thus, there is a pressing need for a secure stable method for authorization management that is easy to manage and simple to operate.

The password authentication unit may be configured for performing password authentication on a mobile UE requesting access for further user security. A method for authorization management provided herein is elaborated below with reference to functions of the modules in the communication UE and of the units in the authenticating module.

Referring to FIG. 3, the method for authorization management herein may include steps as follows.

In Step 100, a communication UE receives a WiFi authentication request sent by a mobile UE requesting access of the communication UE; the flow then goes to Step 200.

In step 100, a receiving module in the communication UE may be configured for receiving the WiFi authentication request, and forwarding the received WiFi authentication request to an authenticating module for processing. The received WiFi authentication request may include unique identification information for identifying the current user of the mobile UE requesting access. The WiFi authentication request sent by the mobile UE requesting access may further include a current MAC address of the mobile UE requesting access. The current MAC address may or may not be sent together with the WiFi authentication request. The current MAC address of the mobile UE requesting access may be sent any time before the connection is formally established, or be sent after the WiFi authentication request is authenticated successfully by the communication UE.

In Step 200, the communication UE authenticates the mobile UE requesting access according to the WiFi authentication request and an authorized list.

In Step 200, the authenticating module may authenticate the mobile UE requesting access. The authorized list saved by a listing unit may include unique identification information for identifying a mobile UE user authorized to access the communication UE. The unique identification information for identifying a mobile UE user saved in the authorized list may be of various types, and may be chosen as related information in an address book of the communication UE, such as a card number of a SIM card or a USIM card in the mobile UE requesting access, an Email account bound to a mobile UE of the user, or other information capable of uniquely identifying the user.

The authenticating module may authenticate the mobile UE requesting access as follows.

In Step 202, a first determining unit determines whether unique identification information in the WiFi authentication request is included in the authorized list; when the unique identification information in the WiFi authentication request is included in the authorized list, the flow goes to Step 204; otherwise when the unique identification information in the WiFi authentication request is not included in the authorized list, the flow goes to Step 400.

In Step 202, the first determining unit may search the authorized list for a file of a type same as that of the unique identification information in the WiFi authentication request. For example, when the received WiFi authentication request contains a card number of a SIM card of the current user, the authorized list may be searched for a card number file of the same type to determine whether the card number of the SIM card of the current user is included in a saved record for users authorized to access the communication UE.

In Step 204, the password authentication unit performs password authentication on the mobile UE requesting access; the flow goes to Step 206 when the mobile UE requesting access passes the password authentication; otherwise when the mobile UE requesting access fails the password authentication, the flow goes to step 400.

In Step 204, a step of WPAPSK password authentication may be included for enhanced user security. In practice, the WPAPSK password authentication may be skipped as excellent security may be achieved with the unique identifier information.

In Step 206, the third determining unit determines whether a number of mobile UEs currently accessing the communication UE has reached an allowed maximal number of mobile UEs accessing the communication UE; when the number of mobile UEs currently accessing the communication UE has reached the allowed maximal number, an On command may be sent to the fourth determining unit, and the flow goes to Step 208; otherwise when the number of mobile UEs currently accessing the communication UE has not reached the allowed maximal number, the flow goes to Step 212.

The allowed maximal number of mobile UEs accessing the communication UE may be set, for example by a user, to avoid poor user experience due to excessive users accessing the communication UE at the same time.

In Step 208, the fourth determining unit is activated/turned on to determined whether a priority corresponding to the current user of the mobile UE requesting access is higher than a priority of a user of a mobile UE currently accessing the communication UE; when there is a mobile UE currently accessing the communication UE with a priority lower than the priority corresponding to the mobile UE requesting access, the flow goes to step 210; when there is no mobile UE currently accessing the communication UE with a priority lower than the priority corresponding to the mobile UE requesting access, the flow goes to Step 400.

Before Step 208, a priority for each user in the authorized list needs to be set, for example as follows. Contact information may be selected from the address book of the communication UE and imported to the authorized list. All the contact information may be imported in batches or once for all. Contact information may be manually added to the authorized list. Contact information in the authorized list may include a name of a contact and unique identification information of the contact. After contact information is included in the authorized list, a priority is to be set for each contact in the authorized list. A “high”, “medium”, or “low” priority may be set for a contact based on a user decision. A default priority may be set, as the medium priority, for example. There may be various ways to set a priority, which will not be elaborated herein.

Referring to Table 1, the authorized list may include various types of data, such as a card number of a SIM card of a user. The authorized list may include a card number of a SIM card or a USIM card of a user, a name of the user, a priority for accessing the communication UE by the user (access priority for short), a MAC address, etc.

TABLE 1 Authorized List (U) card number of SIM card User Name Access Priority MAC Address 136XXXXXXXX Zhang X Medium (default) 00:11:11:11:11:11 189XXXXXXXX Li X High 186XXXXXXXX Wang X Low . . . . . . . . . . . .

In Step 210, the working module disconnects the mobile UE currently accessing the communication UE with the low priority, and the flow goes to Step 212.

In Step 210, a mobile UE currently accessing the communication UE with a low priority may be disconnected in various ways. A mobile UE currently accessing the communication UE with a low priority may be disconnected randomly. Alternatively, one of the mobile UEs currently accessing the communication UE with low priorities that has stayed connected for the longest time may be disconnected.

In Step 212, the second determining unit determines whether the current MAC address of the mobile UE requesting access is included in the authorized list; the flow goes to Step 300.

In Step 212, the authorized list saved by the listing unit may further include the last MAC address used in last accessing the communication UE by a user; when the current MAC address of the mobile UE requesting access is included in the authorized list, the flow goes to Step 214; otherwise when the current MAC address is not in the authorized list, the flow goes to Step 218.

In Step 214, it is determined whether the current MAC address is identical to the last MAC address corresponding to the current user of the mobile UE requesting access; when the current MAC address is identical to the last MAC address corresponding to the current user of the mobile UE requesting access, the current MAC address is sent to the working module, and the flow goes to Step 300; otherwise when the current MAC address is not identical to the last MAC address corresponding to the mobile UE requesting access, the flow goes to Step 216.

In Step 216, the listing unit updates, with the current MAC address, the last MAC address used by the current user in the authorized list; the current MAC address is sent to the working module; and then the flow goes to Step 300.

In Step 218, the listing unit adds the current MAC address of the mobile UE requesting access to the authorized list; the current MAC address is sent to the working module; and the flow goes to Step 300.

In Step 300, the working module connects the communication UE to the mobile UE requesting access according to the current MAC address of the mobile UE requesting access.

In Step 400, the connection is terminated.

Before Step 100, the method may further include: determining whether the communication UE turns on authorization management; when the communication UE turns on authorization management, the flow goes, to Step 100; otherwise when the authorization management function is off, the flow turns to normal authentication.

What described are merely embodiments herein and are not intended to limit the scope of the disclosure.
